Error description
Column or stage variable derivations or constraints which have the below characteristics are evaluated incorrectly a. Functions uses in IF conditions b. These functions take more than 1 parameter c. These parameters are nullable columns or other functions or both nullable columns and other functions. Ex: if (DSLink1.ipcol1 = Substring(DSLink1.ipcol2, 1,DSLink1.len) if (Substring(trim(DSLink1.ipcol1)), DsLink1.len1, DSLink1.len2) = 'abc') The incorrect evaluation can cause rows to be sent to the incorrect output link. Note: For a constraint, we do not need an explicit IF condition. A constraint is always treated as an IF condition.
Local fix
Evaluate the constraint in a stage variable and check the stage variable in the constraint.
